Unable to parse two different objects from JSON Array

Question

I am trying to fetch two different objects from JSON array, but somehow I am unable to fetch second object ("opening_hours"). Not sure if am i Parsing it correctly. I also want to get element "open_now" from "opening_hours" and set it to method "SetAuthor". Below is the code url for JSON array :

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670,151.1957&radius=500&types=food&name=%22%20+%20cafe+%20%22&key=AIzaSyD_kA7xtNYffQNlykVkVGk5ZNQgQtZFZTk

@Override
        protected Boolean doInBackground(String... urls) {
            try {

                HttpGet httppost = new HttpGet(urls[0]);

                HttpParams httpParameters = new BasicHttpParams();

                HttpClient httpclient = new DefaultHttpClient();
                HttpResponse response = httpclient.execute(httppost);
                HttpParams params = httpclient.getParams();

                status = response.getStatusLine().getStatusCode();

                if (status == 200) {
                    HttpEntity entity = response.getEntity();
                    String data = EntityUtils.toString(entity);

                    JSONObject jsono = new JSONObject(data);
                    JSONArray jarray = jsono.getJSONArray("results");

                    for (int i = 0; i < jarray.length(); i++) {
                        JSONObject object = jarray.getJSONObject(i);

                        Elements parameters = new Elements();

                        parameters.setTitle(object.getString("name"));
                        parameters.setImage(object.getString("icon"));

                        elementList.add(parameters);
                    }

                    JSONArray jarraytwo = jsono.getJSONArray("opening_hours");

                    for (int i = 0; i < jarraytwo.length(); i++) {
                        JSONObject objecttwo = jarraytwo.getJSONObject(i);

                        Elements parameterstwo = new Elements();

                        parameterstwo.setAuthor(objecttwo.getString("open_now"));

opening_hours is object, not array. Add json into post instead sharing your api key!. And I recommend you to read about Retrofit and GSON/Jackson. — DeKaNszn

First of all "opening_hours" is a JSONObject not a JSONArray.

Second thing "opening_hours" object inside "result" array.

So parsing should be like this

for (int i = 0; i < jarray.length(); i++) {
     JSONObject object = jarray.getJSONObject(i);

     Elements parameters = new Elements();

     parameters.setTitle(object.getString("name"));
     parameters.setImage(object.getString("icon"));

     elementList.add(parameters);

     // add here
     JSONObject jarraytwo = jsono.getJSONObject("opening_hours");
}

try this JSON parsing

                JSONObject jsono = new JSONObject(data);
                JSONArray jarray = jsono.getJSONArray("results");

                for (int i = 0; i < jarray.length(); i++) {
                    JSONObject object = jarray.getJSONObject(i);

                    Elements parameters = new Elements();

                    parameters.setTitle(object.getString("name"));
                    parameters.setImage(object.getString("icon"));

                    elementList.add(parameters);


                JSONArray jarraytwo = object.getJSONArray("opening_hours");

                for (int i = 0; i < jarraytwo.length(); i++) {
                    JSONObject objecttwo = jarraytwo.getJSONObject(i);

                    Elements parameterstwo = new Elements();

                    parameterstwo.setAuthor(objecttwo.getString("open_now"));

                    Toast.makeText(getApplicationContext(), "open_now : " + objecttwo.getString("open_now"), Toast.LENGTH_LONG).show();

                    elementListtwo.add(parameterstwo);
                }
                }
